Effect of Topical Mitomycin C as an Adjunct to Dilation Therapy in Esophageal Strictures

Background: The treatment of choice for most esophageal strictures is esophageal dilatation but it has a low success rate. This study was conducted to determine the effect of topical mitomycin C as an adjunct to dilatation therapy in esophageal strictures among children.
